To use this pajama set, simply put on the top and shorts. It's perfect for lounging around the house during Christmas or getting a good night's sleep. When it comes to maintenance, you can machine - wash it in cold water with similar colors. Avoid using bleach as it may fade the gingerbread print. After washing, tumble dry on low heat or hang it to dry. Don't iron directly on the print to keep it looking sharp. Enjoy your cozy and festive Christmas in this set!
